Evidence as regards the psycho-genesis rapidly accumulated. Schuster and many other observers refer to the disproportion between the trauma and its results on the nervous system. Severe neuroses arise from minimal shocks, while it is just the severe wounds accompanied by great shock that for the most part are not followed by nervous disturbances. Kurt Singer lays still greater stress on the disproportion between trauma and neurosis, and even endeavours to explain this fact psychologically: “In the kind of psychic trauma that comes on in a flash, in the terror, in the paralysing horror, we are concerned with cases of difficulty or impossibility of adaptation to the stimulus”. In a severe wound there is a discharge of the suddenly increased tension without anything further; when, however, no severe external injury exists the excessive affect is discharged “by means of a sudden abreaction through physical phenomena”. As the Freudian expression “abreaction” shows, psycho-analysis must have been in the mind of the writer when he thought out this theory. The expression sounds like a delayed response to the Breuer-Freudian conversion theory. However, it soon appears that Singer represents this process far too rationalistically; he looks upon the symptoms of the traumatic neuroses as the result of an effort on the part of the patient to find a comprehensible explanation of the (to him) inexplicable morbid process. Thus the work of this author is still far removed from the dynamic conception of the psychical processes of which psycho-analysis has taught us. Hauptmann, Schmidt and others drew attention to the relation in time in the development of the symptoms in the war neuroses. If it is a question of a mechanical injury then the effect should be strongest immediately after the operation of the force. Instead of which one finds that the men thrown into a state of shock still make purposive endeavours to arrange for their safety the moment after the trauma, such as to get to the dressing station, etc., and only after having put themselves under safe conditions do they collapse and the symptoms develop. In some cases the symptoms appear only when the men have to return to the firing line after a period of rest. Schmidt is quite right when he refers this conduct of the patients to the psychical factors; he suggests that the neurotic symptoms develop only after the state of a transitory disturbance of consciousness has disappeared and the men who have suffered the shock re-experience in memory the dangerous situation. We would say: These injured men behave like the mother who rescues her child from a danger which threatens its life with calm imperturbability and disregard of death, but faints after the act has been accomplished. It is immaterial as regards the judgment of the psychological situation that here the person saved was not a beloved stranger, but the beloved person himself.
